TIRE-SECURING DEVICE.

Specification of Letters Patent.

Patented May 25, 1915.

Application filed October 16, 1909. Serial No. 523,029.

T0 all whom t may coneern Be it known that I, BENJAMIN CoPLiN SEATON, a citizen of the United States ot' America, residing at Detroit, in the county of lWayne and State of Michigan, have invented certain new and useful Improvements in Tire-Securing Devises, of which the following is a'specilioation, reference being had therein to the accompanying drawings.

rIlne invention relates to vehicle tires, of that type known as cushion tires, and it is the object of the invention, lirst, to obtain a construction in which the tension of the cushion may be readily adjusted; further, to provide means for readily assembling or dismounting the tire.

To this end, the' invention consists iii various fea-tures of construction, as hereinafter set forth.

In the draiyings,-Figure 1 is a sectional perspective View of the tire: and Fig. is a longitudinal section thereof. j

A is the telly of a vehicle Wheel, of any suitable construction- Upon this telly is mounted a supporting base for the tire case B, said base being preferably formed ot structural steel members C and I). As shown. the member (l is provided with an outwardly extending annular flange E. terminating in a rounded bead I?, and this tlange and bead are adapted to engage a slit in the tire ease ll. rlhe onter member l) is toi-med with a suitably Jrashioned portion (l tor engaging and holding the bead ll on the tire ease. Both members C and D are secured to the telly A by Cross-bolts I. which when seeureigi clamp the parts lirmly in place.

The resilient member or cushion for the tire is in the vlorin ot' in inner annularI .member J which engages the groove or recess, in the outer ease l. This member .l is seated` upon a sectional rim 'K which is arranged between the. members C. 'lhe sections l are seated upon annular members L. preferably of an angular cross section and engaging` the peripl'iery oi the telly A. rI he consti-notion is suoli that by moving the ineinbers L inward or toward each other the n'ieinbers l( will be l'orced outward, thereby enlarging the diameter of the resilient inemlier .l and tori-ing it against the outer (fase l5.

"I is a clamping screw engaging the menibers L, by which the latter'are adjusted toward each other, and N is a spring sleeved.

placing in position the members K and L.

The oase member B may be engaged with the members C and D on one side of the Wheel by slipping the rings L over the telly A, after which the members C and D for the opposite side ot' the wheel are placed in position. It will be noted that the member C may be engaged with the case B by turning back the llap portions l which passesv beneath the iange E. After the parts are assembled, the bolts I are engaged to clamp all of the parts in position.

During the assembling ot the parts the rings L are separated from cach other a suicient distance to relieve all tension from the member J'. but after the parts are sccured in position the bolts M are tightened. moving the members L inward toward each other, and thereby forcing the sections'of the rim K radially outward and expanding the member J. This will place a tension against the outer ease. which may be increased or diminished as desired.

`What I claim as iiiyinvention The combination with a i'elly. of side plates secured thereto having upwardly and outivaidly-extending portions, a tire positioned intermediate of said side plates and seated upon the ont-waidly-extending portions thereof, inner plate members positioned upon opposite sides ot the telly intermediate of said side plates and having upwardly and outwai'dly-extending portions. said outwardly extending portions extending above and being spaced from said side plate extensions and being embedded in the, tire tor clamping the latter to the extensions. In testimony whereoic I :iliix my signature in presence of two witnesses.
